60 is the best compromise between speed and fuel economy.I can't remember where I read this (it was in the 190 forum), but someone posted that a 190 diesel shouldn't be driven over 60 mph. Is there justification for this statement or is it nonsense? Thanks.
I hate that diesel is more expensive than gasoline. It goes through less refining, so it should be less.It truly is a pity that diesel prices are above gasoline. Considering all the sacrifices in acceleration that diesel owners endure, the only way to recoup that cost is by driving on highways in "top gear". The 190D was never really intended for life "on the street,"
A 5-speed would definitely be a huge bonus for dieselers, but it's not much of a drop in engine speed on the highway.It truly is a pity that diesel prices are above gasoline.

I've made a spreadsheet on my computer, and even considering the high price of diesel, my diesel averages 2 cents less per mile than my other most fuel efficient car.
Now I do have to deal with the slow acceleration and 60mph highway speeds, but Id say its still worth the money.
Quite true, diesel taxis are the norm, in fact diesels are much more popular than gassers in Europe . . . diesel fuel in Europe does have significant price advantages, including lower taxes and in some cases, government subsidies. Taxi use is predictable given the cost and relative low maintenance for the OM engines. So, if you're making money from driving in Europe, then a gasser would not be your choice. However, back in the US . . .Your replies were what I thought. Perhaps the author of that sentence really meant to refer to the decreased mileage over 60; I don't know. One reply puzzled me: "these cars were not meant for the street." The 190 was (and probably still is) used widely in Western Europe as taxi cabs (the street). Anyway, I love mine and plan to drive it for years and years (provided I last that long).
Thanks for your replies.
I don't know how you're coming up with these numbers, but they are NOT from the EPA.Let me do a little counting on my fingers...
1984 190E 2.3 4AT: $3.30 per gal / unadjusted EPA Hwy 31MPG = $0.106 per mile
1984 190E 2.2 5MT: $3.60 per gal / unadjusted EPA Hwy 51MPG = $0.071 per mile
That sounds about right. I get 32 city and 37 highway usually on my '84 2.2 autoI have checked the mileage very carefully on my 60K '85 2.0 Euro diesel AT(ca. 35% freeway & 65% 'round town) and I get from 32 to 35 mpg, depending on "the weight of my right foot." Is this in the same range as other diesel owners?
these numbers... are NOT from the EPA.
Again, I don't know how you're coming up with these numbers. These cars never got 51mpg, they will never get 51mpg and the EPA never said so. Hit the link I posted and you can see the before and after adjustment numbers.Sorry tjts1, in the future you may want to do the proper research before stating erroneous information. I quoted MPG from actual results produced by the manufacturer on the track -- before EPA statistical adjustment for estimated MPG.
Here are the raw data entries from the EPA database file (84mfgui.dat), which used to be available for download -- before they had to make their website "idiot proof" so it is only useful for "idiots":
